Abstract
In an open-end spinning process wherein staple fibers are continuously fed to an air vortex and wherein a yarn tail extends into the vortex whereby the fibers affix themselves to and lengthen the tail, the yarn tail is driven at a faster revolution rate than the tail would be driven by the vortex alone by means of a rotary driven member.
